20gb photogaphy plan is difficult to find on the purchase page.
At some point recently, Adobe changed their purchase pages to no longer show the $9.99/mo 20gb Photography plan on their "choose the plan that's right for you" pages. If you had clicked to see Lightroom Classic plans, the only plan they now show (other than the all applications plan) is the $19.99/mo 1TB Photography plan.

And, if you had clicked to see "Lightroom" plans it's the same thing but with the addition of the 1tb $9.99 Lighroom Cloud only plan. In the case of asking to see LrC plans, in order to see the cheaper plan you need to click the "See all Plans and Pricing" text in fine print at the way bottom of the page. In the case of asking about "Lightroom" plans, there are no links that eventually take you to the 20gb $9.99 plan,
I suspect most customers, even those who know the difference between LR and LrC, will not know to seek out the cheaper plan. I think this is a very sad thing for Adobe to do as it really seems to be deceptive marketing.
